Description
Technical field:
The present invention relates to a kind of treatment process of aluminum alloy extrusion section bar, particularly relate to a kind of method of obtaining natural aluminum color for aluminum alloy anode after oxidation.
Background technology:
As everyone knows, aluminium shape surface glossy visual effect is normal after according to antianode oxide treatment in the end-use of field extruded sections such as building slab, electronic cabinet, rack proposes very high requirement for the human consumer, such as, the requirement aluminium section bar should be strong near the surface luster and the metal-like of aluminum metal itself, simultaneously, sense organ effects such as Shamian Island is evenly distributed, and current 6063 aluminum alloy extrusion section bars of routine that adopt are difficult to satisfy above-mentioned requirements after anodic oxidation.
Summary of the invention:
Main purpose of the present invention is to overcome above deficiency and method that the obtaining natural aluminum color for aluminum alloy anode after oxidation of a kind of best over-all properties and physical metallurgy course control method for use thereof is provided.
The technical solution adopted for the present invention to solve the technical problems is: it is made up of sandblasting and anodic oxidation treatment, it is characterized in that: adopt 6063 aluminium alloys, the method for its obtaining natural aluminum color for aluminum alloy anode after oxidation is as follows:
1., 6063 alloy cast ingot optimizing components:
Fe≤0.20％，Si＝0.33-0.5％，Mg≤0.6％，Mn≤0.1％，
Cu＝0.05-0.25％，Ti≤0.05，Zn≤0.05％；
2., full and uniformization of ingot casting processing: soaking temperature is 535-550 ℃, and soaking time is: 8-12 hour;
3., adopt induction heater that ingot casting is carried out the preceding rapid heating of extruding: to solid shape is 450-470 ℃, is 460-480 ℃ to hollow profile;
4., section bar goes out the even cooling behind the nib: adopt uniform air blast cooling, especially more important to big section section bar;
5., section bar or member are carried out the sand blasted surface pre-treatment, abrasive substance is a 120-180 order glass microballon, and air pressure, nozzle and workpiece distance are all adjustable;
6., with hairbrush section bar or member are carried out the labor cleaning;
7., enter the anodic oxidation online treatment as early as possible: do not add any additives and brightener.
The present invention can also adopt following technical measures:
Described induction heater is carried out the preceding rapid heating of extruding to ingot casting;
Described uniform air blast cooling or close in the outlet All-China Federation of Taiwan Compatriots and to use injection water and chilled air cools.
Advantage and positively effect that the present invention has are: make 6063 alloy profile extrusion performances good by material alloysization and physical metallurgy process control, simultaneously, the sand face is evenly distributed after anodic oxidation, and very near the aluminum metal true qualities, technology is simple, and need not add any additives in the anodic oxidation online treatment process and brightener can obtain glossy surface.
Description of drawings:
Fig. 1 is a process flow sheet of the present invention.
Embodiment:
For further understanding summary of the invention characteristics of the present invention and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1.
As shown in Figure 1: the method for obtaining natural aluminum color for aluminum alloy anode after oxidation is as follows:
1., 6063 alloy cast ingot optimizing components: because of considering the influence of chemical ingredients to material homogeneity, smooth surface degree and luminance brightness, must realize that tiny, microscopic crystalline organizing ability homogeneous embodies the chemical ingredients scope of this Metallurgical Quality 6063 alloys after optimizing, wherein the most important thing is the content of iron in the raw material aluminium, its chemical element composition is:
Fe≤0.20％，Si＝0.33-0.5％，Mg≤0.6％，Mn≤0.1％，
Cu＝0.05-0.25％，Ti≤0.05，Zn≤0.05％；
2., full and uniformization of ingot casting processing: soaking temperature is 535-550 ℃, soaking time is: 8-12 hour, because have only the high temperature of employing long-time heating technology, accurate temperature instrumentation and the meticulous control of furnace atmosphere, the aluminium ingot casting of handling through homogenizing just can improve extrusion speed, and high extrusion speed can improve surface of extruded profiles quality and luminance brightness.
3., adopt induction heater that ingot casting is carried out the preceding rapid heating of extruding, also can adopt the conventional type of heating of gas furnace, but consider from anodic oxidation rear surface gloss, two kinds of type of heating effects of the rapid heating of induction heater and the conventional heating of gas furnace are different, low-temperature heat quite provides additional homogenizing process, it is darker to obtain anodic oxidation rear surface color and luster than rapid heating, ingot casting reasonable heated temperature before the extruding: usually, solid shape is 450-470 ℃, and hollow profile is 460-480 ℃;
4., section bar goes out the even cooling behind the nib: adopt uniform air blast cooling, especially more important to big section section bar, also can close and use injection water and chilled air cools in the outlet All-China Federation of Taiwan Compatriots;
5., section bar or member are carried out the sand blasted surface pre-treatment, abrasive substance is a 120-180 order glass microballon, and air pressure, nozzle and workpiece distance are all adjustable;
6., with hairbrush section bar or member are carried out the labor cleaning;
7., enter the anodic oxidation online treatment as early as possible: do not add any additives and brightener.
Its advantage is: 6063 alloy profile extrusion performances are good, and the sand face is evenly distributed after the anodic oxidation, and ten Divide near the aluminum metal true qualities, technology is simple, need not add any interpolation in the online processing procedure of anodic oxidation Agent and brightener can obtain glossy surface.
